During Lync server 2013 installation, the following error received while "preparing current forest":


Error: Active Directory operation failed on "DC1.domain.local". You cannot retry this operation: "Directory object not found 0000208D: NameErr: DSID-0310020A, problem 2001 (NO_OBJECT), data 0, best match of: 'CN=Services,CN=Configuration,DC=sd-develop,DC=local' "

1. verify which domain controller is the scheme master:

1. Open Command Prompt as administrator.
   
2. Type:

4. On the File menu, click Add/Remove Snap-in, and then click Add.

Offline WSUS - clients won't get updates (export and import updates)

We have got two WSUS servers, one is connected to the internet while the other is inside a closed network (due to security). we are using import-export in order to sync the update from the online server to the offline server.
The problem is that after approving a test machine, setting the GPO and checking for new updates nothing happen, the client log reported: "0 updates detected" (full log in RED below), 


Solution: after copying c:\wsus folder from the external server to internal server, exporting and importing (again) the database > clients can get updates.


How to perform export using WSUSutil.exe:


1 ) from external machine open command line and go to %drive%\Program Files\Update Services\Tools folder and type


wsusutil.exe export export_package.cab logfile.log


2) copy the c:\wsus folder to the internal server.


3) copy export_package.cab to the internal server (you don't need to copy the logfile.log)


4) on the internal server run:
wsusutil.exe import export_package.cab logfile.log
